the deformity rate in baby birds from nests in pesticide-sprayed fields is compared to the deformity rate in birds from nests in
mr_godi [17]

In natural experiments, the researcher compares groups exposed or not to exogenous agents, but does intervene in group composition or independent variable modification. This is a natural experiment.

<h3>What is a natural experiment?</h3>

There are two types of investigation strategies,

  • Natural investigation
  • Manipulative investigation

In a natural experiment the researcher does not intervene in the creation of treatment and control groups.

There is an exogenous agent, such as a natural phenomenon, that influences the study groups and that acts as the treatment.

The researcher takes advantage of these events to use these random groups to compare them in the study.

The researcher chooses exposed groups (experimental groups) that might have been affected by the natural event and other groups that have not been affected (control groups).

In the exposed example,

  • Exogenous agent ⇒ Treatment ⇒ pesticide use
  • Exposed group ⇒ Experimental group ⇒ birds from nests in pesticide-sprayed fields
  • Not exposed groups ⇒ Control groups ⇒  birds from nests in unsprayed fields.

Since the researcher does not voluntarily modify the independent variable to observe a response in the dependent variable, this experiment could not be considered to be manipulative.

This is an example of a natural experiment in which the researcher chooses groups exposed to different conditions to compare them and analyze the effect of the pesticide.

Do all human cells obtain glucose in the same way 
kipiarov [429]

Answer:

Animal cells (including humans ofcourse), heterotrophs, derive their energy from coupled oxidation-reduction reactions. Glucose is a primary fuel for heterotrophs. Energy derived from glucose is stored in the form of high-energy phosphate bonds in ATP, or other nucleotide triphosphates, and as energy-rich hydrogen atoms associated with the co-enzymes NADP and NAD .

Glucose is unable to diffuse across the cell membrane without the assistance of transporter proteins. At least 13 hexose transporter proteins with different functions have been identified. Some hexose transporters allow glucose to flow passively from high to low concentration without requiring the expenditure of cell energy. Those that move glucose against its concentration gradient consume energy, generally in the form of ATP.

D-Glucose is the natural form used by animal cells.

So yes it is present inside human cells .
